In-app purchases problem

I purchased Baldur's Gate EE for iPad and purchased the two characters too (Dorn and Neera). The thing is that I had to restore my iPad and reinstall everything. And now I don't have the two in-app purchased characters, how do I get the characters without buying them again?

Do you have an iPad1, Section13? I do, and there seem to be a few problems using this platform. I also bought this character Dorn, and have regretted it, as I can't find him, nor this hitherto invisible restore purchase button.

I cant find a bg1 restore purchase button either. I got a new iPad and all the saves had been restored with iCloud, ect, and my bg2 purchases, but I cant find a restore button in bg1, there was on once though, I seem to remember.
